Abstract
Prezenta inventie se refera la o metoda pentru detectarea fisurilor în lingouri. Metoda, conform inventiei, pentru detectarea fisurilor superficiale în lingouri, prevede încalzirea suprafetei lor printr-un curent de înalta frecventa, concomitent cu deplasarea longitudinala a lingoului printr-o bobina de inductie de înalta frecventa, în timpul acestei deplasari fiind supus unei iradieri cu raze infrarosii pentru înregistrarea distributiei temperaturii de-a lungul sau; în scopul cresterii coeficientilor de emisie ai diferitelor lingouri si al compensarii diferentelor dintre ei, metoda prevede umectarea suprafetei lingoului cu un lichid adecvat, de exemplu apa, eventual cu adaugare de componenti ce realizeaza reduceea tensiunii superficiale, lichidul fiind introdus prin niste orificii amplasate înaintea unitatii de detectare. în scopul analizei la temperaturi sub 0 degree C, metoda prevede ca lichidul de umectare sa fie prevazut cu componente pentru reducerea punctului de înghet, cum ar fi lichide obisnuite antiînghet, ca si alcool.
